Taxonomic revision of the Tabanus nebulosus species group (Diptera: Tabanidae)

Zootaxa (2025)

Maria Carolina Pimenta Dutra Dalton de Souza Amorim Daniel Dias Dornelas do Carmo

The genus Tabanus Linnaeus, 1758 is the most species-rich in the family Tabanidae (Diptera: Brachycera), with about 1,350 valid species. Evidence suggests that the genus is not monophyletic, i.e., there are some smaller clades also with generic rank that phylogenetically fit inside Tabanus. To deal with the complexity of the genus, previous research divided the Neotropical Tabanus fauna into nine groups of species based on morphological similarity. The T. nebulosus group has a considerably uniform morphology among its twelve species and there is evidence that it corresponds to a small clade within the genus. There are records of economic importance of the species of the group. Some species are potential vectors of bovine trypanosomiasis, which causes severe anemia and weight loss in cattle. There are pending issues in the taxonomy of this group, both in terms of a better understanding of the species composition and of species delimitation. This paper corresponds to a taxonomical review of the species related to T. nebulosus. Here we provide a diagnosis of the known species of the group, a pictorial key with high-definition images, and updated distribution maps for the valid species. Also, considering the limits of each species based on a careful morphological assessment of the group, the status of Tabanus ornativenris Kröber is evaluated and Tabanus vestigium sp. nov. is described from the state of São Paulo, Brazil.

Vertical stratification of insect abundance and species richness in an Amazonian tropical forest

Scientific Reports (2022)

Dalton de Souza Amorim Brian V. Brown Danilo Bôscolo Rosaly Ale‐Rocha Deivys M. Alvarez García

Abstract Tropical forests are among the most biodiverse biomes on the planet. Nevertheless, quantifying the abundance and species richness within megadiverse groups is a significant challenge. We designed a study to address this challenge by documenting the variability of the insect fauna across a vertical canopy gradient in a Central Amazonian tropical forest. Insects were sampled over two weeks using 6-m Gressitt-style Malaise traps set at five heights (0 m–32 m–8 m intervals) on a metal tower in a tropical forest north of Manaus, Brazil. The traps contained 37,778 specimens of 18 orders of insects. Using simulation approaches and nonparametric analyses, we interpreted the abundance and richness of insects along this gradient. Diptera, Hymenoptera, and Coleoptera had their greatest abundance at the ground level, whereas Lepidoptera and Hemiptera were more abundant in the upper levels of the canopy. We identified species of 38 of the 56 families of Diptera, finding that 527 out of 856 species (61.6%) were not sampled at the ground level. Mycetophilidae, Tipulidae, and Phoridae were significantly more diverse and/or abundant at the ground level, while Tachinidae, Dolichopodidae, and Lauxaniidae were more diverse or abundant at upper levels. Our study suggests the need for a careful discussion of strategies of tropical forest conservation based on a much more complete understanding of the three-dimensional distribution of its insect diversity.

The identity of Paratrizygia conformis Tonnoir (Diptera, Mycetophilidae), with comments on its systematic position

Zootaxa (2011)

Dalton de Souza Amorim Sarah Siqueira Oliveira Erica McAlister

Paratrizygia conformis, the type–species of the genus Paratrizygia, from Tasmania, is redescribed from the holotype. The wing venation and male terminalia are illustrated in detail. The question of the monophyly of the genus—which has four additional species in Chile and southern Argentina, and four species in the Atlantic Forest, in Brazil—is addressed. Comments are made on the relationships of the genus in the Azana–group of Sciophilinae. The hypothesis of monophyly of Paratrizygia is retained, as indicated by the presence of modified, elongated spines on a distal fold of tergite 9.
